Question

If the sum of a number and four is multiplied by two, the result is 28. What is the number?

Answer 1

Answer:

10

Step-by-step explanation:

The sum of a number and 4 is multiplied by 2, and the result is 28. In other words, letting the unknown number be x:

$2(x+4)=28$

Solve for x. Divide both sides by 2:

$x+4=14$

Subtract 4 from both sides:

$x=10$

So, our unknown number is 10.

And we're done!

Answer 2

Answer:

10

Step-by-step explanation:

Let the required number be x

2(x+4) =28

x + 4 = 28/2

x + 4 = 14

x = 14 - 4

x = 10
